SPECIFICATION `forming part of Letters Patent No. 747,154, dated December 15, 1903.

Application tiled September 8, 1902. Serial No. 122,636. (No model.)

.To all whom t may concern:

Be it known that I, LOUIS DURAND, a citi* zen of the United States, and a resident of Dumont, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Dough-Kneading Machinery, of which the following is a specitication.

This invention relates to a type of dough mixing and kneading machines designed for the production of a comparativelylarge batch of dough, said type embodying ahorizontallyrotatable pan of liberal capacity, together with a stirrer and kneader, both revolubly coactive Within the pan, a pivotal pan-support being present for permitting the pan to be tilted when desired for the more convenient removal of the dough. f

A prominent object of the present invention is to so locate the bearing-points of the pivotal pan-support with respect to the other parts of the machine that the load of the pan Will be more nearlyequalized duringworking.

A further object is to dispose certain parts connected with the gearing in a plane above the pan and its tilting axis, whereby a counterbalance tendency for the pan results, thus rendering it more readily operable for the removal of the dough.

With the above and other purposes in view my novel dough mixing and kneading machine comprises a tilting pan-support having suitably-mounted trunnions in a horizontal plane contiguous with that of the upper portion of the pan, together with certain parts pertaining to the actuating-gearing and which tend to counterbalance said pan and its load.

There are other important features and details connected with the invention,which, besides those previously alluded to, are clearly set forth in the subsequent extended description.

In the accompanying drawings, forming part of this specification, Figure 1 is an elevational View, partly in section, of a dough mixingand kneading machine embodying my invention. Fig. 2 is a plan view of the machine represented in Fig. 1, and Fig. 3 isa vertical end View.

Similar reference characters are employed to designate corresponding parts in the several gures of the drawings where they occur.

Suitable standards A B are mounted on the bed-plate O and are provided at their upper portions with bearings 2 2, in which bear the trunnions 3V 4 of the pan-support, which is shown as being in theform of a swinging yoke D, embodying a lower part depressed relative to the plane of the truunions and pendently supported between the standards. Many of the Working parts of the machine are carried by. this yoke.

The pan E, in which the combined mixing and kn'eading operation is to be conducted, is of comparatively liberal capacity and also of such depth and diameter that when in position within the lower part of the yoke its upper portion will be in a plane proximate i with that'of the trunnions. The pan is attached to a central vertical shaft 5, revolubly resting in a step-bearing 6 in the lower horizontal bar of the yoke D, the upper cross-bar ofthe yoke having a bearing '7, through and above which the shaft extends for the connection of the bevel-gear 8 and spur-gear 9, the latter meshing with a gear 10, secured to the upper end of a shaft 1l, rotatably suspended from said upper bar and carrying within the pan the vertical stirrer 12.

On the inner end of an upper horizontal counter-shaft 13. is keyed a bevel-pinion 14E, meshing with the gear 8. 'Ihe shaft 13 turns in suitable bearings 15 16, mounted on the upper bar of the yoke. Also on the shaft 13 are key'ed the angle-pinion 17 and gear 18, the former meshing with an anglegear 19 for rotating the inclined kneader 20, through the the medium of the shaft 2l, revolubly supported in the extended inclined bearing 22 on the adjacent upright of the upper portion of the yoke.

23 designates the main driving-shatt revolubly mounted in the bearings 24: 25, carried by the bracket F, attached externally on the standard B. To the said driving-shaft is secured the driving-pulley 26 and pinion 27, the latter meshing with the intermediate gear 28, turning on a stub-shaft 30, carried by a member 29, pivotally connected at its ends with the counter and driving shafts, respec- IOO tively. It will be observed that on account of the shaft 23 being concentric relative to the trunnion-axis of the yoke and, further, by 'reason of the employment of the member 29 the motion-transmitting pinion 27 will always be in mesh with the intermediate gear 28, irrespective of the swinging position of the yoke.

In `order to dump the pan E, the pan-support constituted by the yoke is tilted by means including a hand-wheel 31, secured on the outer end of a short horizontal shaft rotatably supported in a bearing on the standard A and transmitting motion by bevelgears 32 to a horizontal worm 33 at the inner side of the standard and meshing with a worm-gear segment 34, rigidly attached to the yoke D.

The operation and functions of the machine will be readily comprehended. The components for the production of the dough being introduced into the pan in the requisite proportions, the rotation of the pulley 26 will revolve the shaft 23, which through the medium of the coacting gearing will eect the horizontal rotation of the pan E and coincident rotation upon their axes of the stirrer l2 and kneader 20. When the dough is properly mixed and kneaded, it can be dumped into a receptacle G, notwithstanding the continued rotation of the pan, stirrer, and kneader gearing, the rotation of the hand-Wheel causing the pan -support to tilt and with it the pan, the power required to dump the pan being minimized by the counterbalancing or load-equalizing effect resulting from the location `of the yoke-trunnions in a plane contiguous to the top of the pan and the disposition of other parts coperating to produce such effect. i

The feature involving the integral relation of the depressed part of the yoke, the trunnions, yoke-uprights, and upper cross-bar: besides conferring great strength to the ma-l chine also presents a simple and efficient medi'nm enabling the convenient assemblage and location of the various parts more directly situated with respect to the pan.

It will be comprehended that by the described arrangement of pan-dum ping devices, including the worm and worm-gear segment,

Ithe pan can be tilted to any required extent and be automatically held in any of its tiltedy positions by such worm engagement, which latter, in addition to its capacity for communicating the motion required to accomplish the tilting, possesses the capability of self-retaining the pan in any position to which it may be tilted. These dual functions of the worm and gear-segment are present coincidently during the actuation of the mixer and kneader, which can obviously contiue to work during any tilting movement or while the parts'are held in any tilted position.
